Omron NSJ CONTROLLERS - 03-2008 Operation Manual page 26

Application Precautions
• Unexpected operation may result if inappropriate data link tables or
parameters are set. Even if appropriate data link tables and parameters
have been set, confirm that the controlled system will not be adversely
affected before starting or stopping data links.
• CPU Bus Units will be restarted when routing tables are transferred from
a Programming Device to the NSJ Controller. Restarting these Units is
required to read and enable the new routing tables. Confirm that the sys-
tem will not be adversely affected before allowing the CPU Bus Units to
be reset.
• Do not connect an USB connector to any device that is not applicable.
• Before connecting an USB connector to a device, make sure that the
device is free of damage.
• Do not press the touch switch with a force greater than 30 N.
• Confirm the safety of the system before pressing touch switches.
• Do not accidentally press touch switches when the backlight is not lit or
when the display does not appear.
• Signals from the touch switches may not be input if the switches are
pressed consecutively at high speed. Confirm each input before proceed-
ing to the next one.
• Before initializing screen data, confirm that existing data is backed up at
the NS-Designer.
• When changing the password with the system menu, do not reset or turn
OFF the power supply until writing is finished (i.e., until the Write Button
returns to its original condition). It may become impossible to manipulate
screens if the password is not set correctly.
• When using the device monitor, confirm the safety of the system before
performing the following operations.
• Changing monitor data
• Changing operation modes
• Forced setting or resetting
• Changing present values or set values
• To ensure safety, always set upper and lower limits when using the
numeral input function.
• Do not use benzene, paint thinner, or other volatile solvents, and do not
use chemically treated cloths.
• use chemically treated cloths.
• When connecting pin 6 (+5 V power supply line) of serial port A or B (RS-
232C ports on the Display Section) to any external device, make sure that
the current capacity of the connected device is 250 mA max.
• Do not connect pin 6 (+5 V power supply line) of serial port C (RS-232C
ports on the Controller Section) to any external device except the CJ1W-
CIF11 RS-422A Adapter or NT-AL001 RS-232C/RS-422A Adapter. Doing
so may damage the external device or NSJ Controller.
• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.
• When backing up the system, use the correct Memory Card slot, as
shown in the following table.
